computer vulnerability note 20339

SQLite: NULL pointer dereference

Synthesis of the vulnerability

An authenticated attacker can force a NULL pointer to be dereferenced in SQLite, in order to trigger a denial of service.
Impacted products: SQLite.
Severity: 2/4.
Consequences: denial of service on service, denial of service on client.
Provenance: user account.
Creation date: 09/08/2016.
Identifiers: VIGILANCE-VUL-20339.

Description of the vulnerability

The SQLite product can use SELECT queries to join tables.

The COLLATE NOCASE operator disables the case sensitive comparison for strings.

However, the usage of join functions including an integer variable with the NOCASE operator (corresponding to a non-existent COLLATE sequence because it is not a string) causes the usage of a NULL pointer.

An authenticated attacker can therefore force a NULL pointer to be dereferenced in SQLite, in order to trigger a denial of service.

computer vulnerability alert CVE-2016-6136

Linux kernel: memory corruption via audit_log_single_execve_arg

Synthesis of the vulnerability

An attacker can generate a memory corruption via audit_log_single_execve_arg() of the Linux kernel, in order to trigger a denial of service, and possibly to run code.
Impacted products: Debian, BIG-IP Hardware, TMOS, Fedora, Android OS, Linux, RHEL, Ubuntu.
Severity: 2/4.
Consequences: administrator access/rights, denial of service on server.
Provenance: user shell.
Creation date: 09/08/2016.
Identifiers: 120681, 1353533, CERTFR-2016-AVI-315, CERTFR-2016-AVI-334, CVE-2016-6136, DLA-609-1, DSA-3659-1, FEDORA-2016-30e3636e79, FEDORA-2016-754e4768d8, K90803619, RHSA-2016:2574-02, RHSA-2016:2584-02, RHSA-2017:0307-01, USN-3084-1, USN-3084-2, USN-3084-3, USN-3084-4, USN-3097-1, USN-3097-2, USN-3098-1, USN-3098-2, VIGILANCE-VUL-20336.

Description of the vulnerability

The Linux kernel implements audit features.

The audit_log_single_execve_arg() function of the auditsc.c file checks its parameters obtained via copy_from_user(). However, this function then reuses the value from the user space area, which may have been modified after the check.

An attacker can therefore generate a memory corruption via audit_log_single_execve_arg() of the Linux kernel, in order to trigger a denial of service, and possibly to run code.

vulnerability announce CVE-2016-6187

Linux kernel: privilege escalation via apparmor_setprocattr

Synthesis of the vulnerability

A local attacker can generate a memory corruption via apparmor_setprocattr() on the Linux kernel, in order to escalate his privileges.
Impacted products: Linux.
Severity: 2/4.
Consequences: administrator access/rights, privileged access/rights, denial of service on server.
Provenance: user shell.
Creation date: 08/08/2016.
Identifiers: 1354383, CVE-2016-6187, VIGILANCE-VUL-20332.

Description of the vulnerability

The AppAmor module can be installed on the Linux kernel.

The proc_pid_attr_write() function uses memdup_user for memory management, so the array containing parameters of the apparmor_setprocattr() function can exceed the current memory page. This function writes a '\0' character at the end of the array if it is not present. However, the position of this character is not sufficiently checked, which may allow to write in a bad memory area.

A local attacker can therefore generate a memory corruption via apparmor_setprocattr() on the Linux kernel, in order to escalate his privileges.
